|Description||string||An association derived from AttachedElement for use in attaching a FileSystem to a LogicalFile (or Directory). The semantics of this relationship require that the SystemElement LogicalFile be contained by a FileSystem (via the FileStorage association) that is different from the FileSystem referenced as the SameElement. The LogicalFile's containing FileSystem could be either local or remote. For example, a LocalFileSystem on a Solaris ComputerSystem can mount on its LogicalFile a FileSystem accessed via the machine's CDROM drive, i.e., another LocalFileSystem. On the other hand, in a 'remote' case, the LogicalFile must be surfaced in the namespace of the local host appropriately.
